If you thought you'd heard the last of Kanye West and Taylor Swift's feud, just wait till you read the bombshell Kim Kardashian dropped while telling her side of the story to GQ magazine. And Taylor's lawyers are furious!

In her most incisive interview yet, the 35-year-old reality star got the claws out for Taylor, 26, claiming she and Kanye have video proof of Taylor approving Kanye's controversial lyric for his song 'Famous'. Yep, it's this line: "I feel like me and Taylor might still have sex. Why? I made that b--- famous."

At the time, Taylor denied the conversation and slammed Kanye, 39, in a fiery Grammys speech targeting people "who try to undercut your success or take credit for your accomplishments or your fame".

Over to you, now, Kim. "She totally approved that," Kim told GQ. "She totally knew that that was coming out. She wanted to all of a sudden act like she didn't."

"I swear, my husband gets so much s--- for things [when] he really was doing proper protocol and even called to get it approved.

"What rapper would call a girl that he was rapping a line about to get approval?"

This is where it gets ugly. Kim explained that a videographer was filming Kanye making the phone call, because EVERYTHING Kim and Kanye do is filmed.

Not for Keeping Up With The Kardashians, of course – he's barely a ghost on that show – but Kanye commissions videographers to film his entire process of recording an album for potential future use.

"[Taylor] totally gave the okay," Kim continued. "[Producer] Rick Rubin was there. So many respected people in the music business heard that [conversation] and knew.

"I mean, he's called me a bitch in his songs. That's just, like, what they say. I never once think, 'What a derogatory word! How dare he?' Not in a million years. I don't know why she just, you know, flipped all of a sudden.

"It was funny because [on the call with Kanye, Taylor] said, 'When I get on the Grammy red carpet, all the media is going to think that I'm so against this, and I'll just laugh and say, 'The joke's on you, guys. I was in on it the whole time'. And I'm like, wait, but [in] your Grammy speech, you completely dissed my husband just to play the victim again."

But here's the clincher: Kim says she and Kanye haven't released the tape of Taylor "approving" the song because of a snarky legal letter from Team Swift.

Somehow Taylor's people knew she was being recorded, but Kim isn't sure how. What she did say was that when filming "you don't stop every two seconds and be like, 'Oh wait, we're shooting this for my documentary'."

Kim added: "You just film everything, and whatever makes the edit, then you see, then you send out releases. It's like what we do for our show." Because life is just a show, right?

GQ confirmed with Kanye's people that they definitely filmed the chat and received correspondence from her lawyers, but would not provide the proof.

Now we bet you're dying to hear Taylor's response to all of that. A spokesperson for the 'Shake It Off' singer provided a statement to the magazine, which reads:

Taylor does not hold anything against Kim Kardashian as she recognises the pressure Kim must be under and that she is only repeating what she has been told by Kanye West.

However, that does not change the fact that much of what Kim is saying is incorrect. Kanye West and Taylor only spoke once on the phone while she was on vacation with her family in January of 2016 and they have never spoken since.

Taylor has never denied that conversation took place. It was on that phone call that Kanye West also asked her to release the song on her Twitter account, which she declined to do.

Kanye West never told Taylor he was going to use the term 'that bitch' in referencing her. A song cannot be approved if it was never heard. Kanye West never played the song for Taylor Swift. Taylor heard it for the first time when everyone else did and was humiliated.

Kim Kardashian's claim that Taylor and her team were aware of being recorded is not true, and Taylor cannot understand why Kanye West, and now Kim Kardashian, will not just leave her alone.
